I just recently discovered navidrome https://www.navidrome.org
I converted all my old CDs to ogg and installed navidrome on my home server. Basically, now I have my own personal spotify.
I am aware though that this solution won't work for everybody.
Too late, the library has all of the discs now. :-)
She could borrow them all back, one at a time, and re-build the library.
